Answer:

one that has an unstable nucleus

Explanation:

An isotope is defined as a chemical variant present in an atom with different number of neutron but same number of protons.

Radioactive decay is the sudden breakdown of an atomic nucleus allowing matter and radiation to be emitted from the nucleus. A radioisotope with unstable nuclei undergoes radioactive decay because they do not have adequate binding energy to keep the nucleus together. there are four types of Alpha, Beta, Gamma Decay and Positron Emission.

Hence, the correct option is "one that has an unstable nucleus"

Explanation:

The peripheral nervous system has two distinct divisions with different functions. The sensory or afferent division is one of them. The sensory or afferent division serves to deliver the sensory information from the receptors to the central nervous system. The neurons that carry sensory information are called sensory neurons. Cranial nerve II carries the sensory impulses about vision from the retina to the brain (a part of the central nervous system). This makes this nerve a component of the sensory division of PNS.
